Soil deterioration, mostly from wind erosion, is a defining feature of land degradation in the Sahel. This is aided by anthropogenic reasons like population increase, intensified agriculture, and overgrazing, as well as environmental variables like drought and declining rainfall. Anthropogenic and climatic variables may influence one another or operate independently. In order to preserve soil fertility and minimize erosion losses, these variables lead to a drop in plant cover, a reduction in fallow times, and a reduction in the balance between cultivated fields and fallow areas. In the Sahel, sustainable land methods including agroforestry, integrated farming, and vegetation-cover-promoting techniques are suggested. These will boost agricultural yield per unit of land and provide soil cover to shield soils from erosion-causing factors. These will improve agricultural output and alleviate land degradation by increasing agricultural productivity per unit land area, diversifying farmers’ sources of income, and providing soil cover to shield soils from agents of erosion.
